DIAGNOSIS. Total length of adult females 40–42 mm , males unknown. Coloration pale yellow to light orange, chelicerae yellow without reticulation. Pedipalp chela length/width ratio 3.4–4.2 in females; pedipalp fingers of females straight ( Fig. 211 ); dentate margin of movable finger armed with 7 rows of granules, and a short apical row of 4 denticles ( Fig. 9 ); most proximal granule row with one external accessory granule. Pectines with 19– 21 teeth. Metasoma very narrow, metasoma V length/ width ratio is 2.30–2.46 in females ( Figs. 79 ); metasoma I with 10 carinae, II–IV with 8 carinae. Telson setose, bearing numerous long macrosetae and short, pointed subaculear tubercle; vesicle smooth, ellipsoidal, slightly bulbous, telson length/depth ratio 2.78–2.88; aculeus slender, curved, shorter than vesicle. DESCRIPTION. Total length of adult females 40–42 mm , males unknown. Measurements of the carapace, telson, segments of the metasoma and segments of the pedipalps are given in Table 2 . Base color base is pale yellow to light orange ( Figs. 206–218 ). Chelicerae are yellow without reticulation. ( Fig. 208 ). Sexual dimorphism unknown. PEDIPALP ( Figs. 210–217 ). Pedipalp mostly very sparsely hirsute, more densely so on ventral surface of movable finger. Femur granulated, with five granulose carinae. Patella almost smooth with seven granulose carinae. Chela smooth with traces of carinae visible; fingers long, curved, with 7 granule rows and short apical row of 4 denticles on dentate margins; the most proximal row with one external and no internal granule. Pedipalp fingers straight in females. CARAPACE ( Figs. 206 , 208 ). Slightly trapezoidal (narrower anteriorly) and slightly longer than wide, or as long as wide; anterior margin convex, with some short microsetae. Carination absent. Median and posterior lateral furrows wide and deep, others vestigial to absent. Tegument densely and coarsely granulose. Median eyes large and raised; four or five pairs of lateral eyes: three major ocelli aligned along each anterolateral corner, plus two minor ocelli that are vestigial to absent. MESOSOMA ( Figs. 206–209 ). Tergites I–VI bear a single conspicuous median carina; tergite VII bears five well defined carinae (median, submedians and laterals), which are long and serrate to crenulate. All tergites densely and coarsely granulose mainly on posterior parts. Sternum type 1, triangular in shape; medial depression large. Pectines extending to around end of sternite III in females. Tooth count 19–21 (mean 20, 6 ♀ combs). Pectines with 3 marginal lamellae and 7 middle lamellae. Sternites lack carinae, surfaces smooth and sparsely setose. Posterior margin of sternite V without smooth median patch in both sexes. Sternite VII with four well defined carinae. LEGS ( Figs. 103–106 ). The tarsomeres bear two rows of macrosetae on their ventral surface and numerous macrosetae on other surfaces; bristle combs absent. Femur bears only solitary macrosetae. Femur coarsely granulose, femur and patella with carinae developed. Moderate tibial spurs present on leg IV. METASOMA AND TELSON ( Figs. 78 , 87 , 245–247 ). All segments with granulate, completely developed carinae. The carinae are composed of minute, rounded, equalsized, and evenly spaced granules. The first metasomal segment has a total of 10 carinae, the second through fourth segments have eight carinae, and the fifth segment has five carinae. All metasomal segments are very sparsely granulated. Metasoma is very sparsely hirsute. Telson smooth with only a weak trace of a ventral carina and a dense cover of long setae mainly on the ventral surface. Subaculear tubercle short and pointed. Vesicle elongate, ellipsoidal, telson length/depth ratio 2.78–2.88 in females. Aculeus curved, shorter than vesicle.
